HARVESTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 252,681, dated January 24, 1882.

Application filed April 23,1881. (No model.)

The invention relates more particularly to that class of harvesting-machines in which the knife is driven by a vibrating arm from a differential oscillating gear-wheel mounted on the frame ot'the machine and operated by atoothed wheel on the master-wheel of the machine.

The invention consists in the combination,

with the said vibrating arm and connections, of an oblique brace arranged underneath said arm, with one end connected to the outer end of said arm by a ball-and-socketjoint and the other end connected-by a similar joint to the main frame at a point below the mainaxle, for the purpose of bracing and supporting the vibrating arm while permitting it to vibrate.

1n the drawings,.Eigure 1 is a plan of the machine. Fig. 2 is a side elevation. showing the brace. Fig. 3 is a detail of the frame.

A is the traction-wheel of the machine; BB, the differential driving-gear.

O is the vibrating arm, which actuates the cutter; and D the irame of the machine, provided with the arm D, which connects with the inside shoe of the cutting apparatus.

It will be seen that an oblique brace connected in this manner to the parts specified will support and brace the vibrating arm without interfering with its vibrating movement.

What I claim as my invention is In aharvesting-machine, the combination, with the differential gearing B B and vibrating arm 0 for operatingthe cutter-bar, of the oblique brace F, arranged underneath said arm, one end of said brace being connected by a. ball-and-socketjoint to the outerend of said arm and the other. end connected by a similar joint to the main frame of the machine at a point below the main axle, whereby the vibrating arm is braced and supported while it is permitted to vibrate, substantially as described.
